Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133786, here are decompositions:
- 5 + 133781 = 133786
- 17 + 133769 = 133786
- 53 + 133733 = 133786
- 89 + 133697 = 133786
- 113 + 133673 = 133786
- 137 + 133649 = 133786
- 227 + 133559 = 133786
- 293 + 133493 = 133786
Showing the first eight; more decompositions exist.
